OSE 40mm x 74mm motors

[Brushless55]

BEWARE !!! I don't know how your motor is but mine is
- JUNK - I ran it yesterday, and it came apart at the bullet ( no solder ) in a min - never got above 90* in my DF33 with a X645. It took out a brand new T-180 ESC when it unconnected. When I fixed it ( re-soldered ) it cogged terribly, the wires got very hot, it would not run and had to unhook it quickly before it ruined another T-180 ESC
I'm sending the motor and controller back to OSE.

That sounds like a 8XL keda motor I had in my Mean Machine.. It took out a 200A esc and the motor went to the dark side

What packs were you running?

[RCKong]

I was running 2 4s 40c 5000mah Turnigys... plenty of juice -
I'm pretty sure these motors are KEDA's

May I ask why you start your testing with a x645 with a 2350kv motor in a mono?

[ray schrauwen]

I was going to ask that....?

Keda or Leopard, all good motors.

[RCKong]

Thats a prop or 2 down from what I run with my leopard 2200. It did not make it 3 times around the pond and failed. It took about 2 min to get the boat in via fishing pole, and it temped at 85* so I figured it was under 100* when it popped. Set up is not the issue. The reason it failed is because there was only a small spec of solder on the entire connection !!! Out of the 3 wires only 1 had any solder in it.

Are you guys running with the stock (4mm) bullets? Don't you switch to at least 5.5mm?

[tiqueman]

They came w/ 5.5s

After hearing RCK's whoa's, I pulled the shrink back on all three wires of my motor to inspect the joints and there is VERY little solder in the connections - an extremely shoddy job of soldering IMHO. I'm not going to run the motor with the connectors like they are, and I don't feel it's my job to make it right.

[ray schrauwen]

John, the factory solder joints are sometimes alot to be desired. I redo them all.

Mine were like that too but its not a big deal to me. I go over each lead and resolder each motor I have that comes in. Heck for most I have to adapt to my bullet preference anyways. On some its 5.5, others its 6mm and on the bigger motors its 8mm bullets. But I have that ounce of prevention mentality when it comes to all my components.

Looking forward to running this motor sometime in the next month when I get back from the road. It certainly feels like a torquey little bugger on 4S.

So, alsmost 2400kv. On 4s with a x645, in a DF33?!?!?!? That is a recipe for disaster. LOTS of amps there, man.

[Insaniac]

Are these Leopard clones?

[Rumdog]

a clone of a clone of a clone. Chances are, they all come from the same place. Some with different components.

[ray schrauwen]

Yes, I have bought and sold one of those. Only sold it because I wanted the 4082 2200kv from Steve.
